A woman's hair colour can often dictate every aspect of her life, from the way she dresses to her mood.
So it's not the kind of thing that can be taken lightly - or darkly, as it has been in the case of Fearne Cotton.
The BBC presenter recently dyed her blonde locks brown, and seems to be dressing accordingly too.

Miss Cotton, 28, was pictured in a black, gothic-inspired outfit with lace tights, ankle boots with studded straps, a 20s-style dress and a jacket as she left the BBC Radio One studios.
The change of hair colour occured for Sport Relief last week.
Fearne dyed her hair both red and brown for the charity fundraiser but seems to have settled with the new darker hair colour.

Earlier this month she completed a 1,000 mile cycle ride from John O'Groats to Land's End with a team of celebrity friends.
Along with a team of seven stars she helped to reach a target of £1million for Sport Relief.
The team of seven riders, which also included Miranda Hart, Russell Howard, Patrick Kielty and Jimmy Carr, posed in fluroscent yellow jackets by the famous Land's End signpost after finishing the challenge.

Fearne found the challenge harder than most.
Speaking as the event neared its end, she said: 'We know that we need to try and keep something in reserve for the hills in Cornwall but to be honest I'm just running on empty now anyway so we will just have to see how it goes.'
The presenter had previously fallen off her bike during two training sessions, and was unsure how she would manage with such a daunting challenge.
